THE BUSINESS CASE
Why Build a Decentralized OAuth Provider
Decentralized OAuth 2.0 moves identity from a cost center to a strategic asset. It eliminates vendor lock-in, reduces compliance overhead, and unlocks new revenue streams through user-owned data.
Architectural Comparison
Centralized OAuth vs. Decentralized OAuth
Key differences between traditional OAuth providers and our decentralized OAuth 2.0 solution for Web3 applications.
| Architectural Factor | Traditional OAuth (Google, Auth0) | Chainscore Decentralized OAuth |
|---|---|---|
Data Ownership & Privacy | Provider controls user data | User controls data via self-custody |
Single Point of Failure | Yes (provider outage) | No (decentralized network) |
Censorship Resistance | Low (provider can revoke access) | High (permissionless, on-chain) |
Integration Complexity for Web3 | High (requires custom bridging) | Native (built for wallets & dApps) |
Compliance & Audit Trail | Opaque, proprietary logs | Transparent, immutable on-chain logs |
User Onboarding Friction | Email/password, 2FA | Wallet connection (1-click) |
Infrastructure Cost | Recurring SaaS fees per MAU | Predictable gas-based model |
Time to Implement | 2-4 weeks | < 1 week |
Default Security Model | Trust the central provider | Trust minimized via cryptography |

PROVEN METHODOLOGY
Our Development & Deployment Process
A structured, security-first approach to delivering production-ready Decentralized OAuth 2.0 infrastructure. We focus on rapid integration, enterprise-grade security, and measurable outcomes.
01
Architecture & Design Sprint
We conduct a 1-week collaborative sprint to design your OAuth 2.0 flow, define token standards (ERC-20, ERC-721), and architect the smart contract suite. This ensures alignment on technical requirements and user experience from day one.

Technical & Commercial FAQs
Decentralized OAuth 2.0: Common Questions
Answers to the most frequent questions from CTOs and product leads evaluating decentralized identity solutions.
A standard implementation for a production-ready Decentralized OAuth 2.0 provider takes 2-4 weeks. This includes protocol integration, smart contract deployment, backend API development, and security audit integration. Complex enterprise integrations with existing IAM systems may extend to 6-8 weeks. We provide a detailed project plan within the first 3 days of engagement.
